People who keep a large snake in their apartment building, which happens quite a bit, all of a sudden, within two summers, have a 14-foot animal that's eating adult rabbits, and needs quite a bit of room and quite a bit of heat. That's the animal that gets put in the back of a pick-up truck and dumped into the Florida Everglades or the city lake, or just left on a doorstep - again, it's quite often the animal that suffers.
We often say that psi is like musical ability: it is widely distributed in the populate, and everyone has some ability and can participate to some extent - in the same way that the most nonmusical person can learn to play a little Mozart on the piano. On the other hand, there is no substitute for innate talent, and there is no substitute for practice.
